I have the Borla Cat Back and it sounds amazing..especially with the KnN cold air intake. at idle it sounds healthy but in no way obnoxious but when you step on the gas it comes alive!! very pleased with this set-up, no drone noise whatsoever. ~K

I have the ready lift 2 1/4 front leveling kit installed on my 15 Denali. I also had the Dealership install the sensor kit to get the magnetic ride to function properly. Now it rides like my wife's 2015 Yukon Denali ~K€.
